“…However, RO power consumption has been reduced since the invention of ERD [2,11]. Without ERD, the energy requirement for desalinating seawater at standard salinity of 35 g/L is approximately 4 kWh/m 3 [2,[11][12]. With an ERD, the energy requirement for standard seawater desalination is about 2 kWh/m 3 [12,13].…”
